GEAR-SHIFT MECHANISM.

Application filed December 23, 1919, Serial No. 346,901.

To all whom it may cmi-cern.'

Be it known that I, Louis MoRINsnY, a citizen of Russia, and a residentof the cit \,1 of New York, county of Bronx, and State of New York, haveinvented certain new and useful Improvements in Gear-Shift Mechanism, ofwhich the following is a specilication.

The invention relates to shift mechanism for the change speedtransmission gearing of automobiles, and more particularly to that typeof gear shift mechanism in which the desired setting of the gears islirst selected by suitable means such as a hand lever located on oradjacent the steering wheel, and is then effected under control of a.foot pedal or the like which also usually controls the clutch.

The invention seeks to provide a simple, compact mechanism in which theseveral gear sliifters are set in proper selected posi tions by a commonactuating member or ram having tappet and "am elements arrangedrespectively to set the shifters in active and neutral positions.Further ob ljects of the invention are to provide a construction inwhich, after the mechanism has been once set in a given selectedcondition, it will remain in such condition until a new selection ismade, irrespective of the number of times the clutch pedal is depressedand also to provide the actuating member or ram with spaced,neutralizing cams which, in the different selected positions of theactuator, will first neutralize one of the gear Shifters and loclr it inneutral position, while the other shifter is being set in activeposition.

The invention also seeks to provide, in connection with the shiftermechanism, an improved lock for preventing unauthorized operation of thegear shift mechanism; also to provide improved means for effecting theoperation of the clutch and shift mechanism.

Vith the above mentioned objects in view, the invention consists in thefeatures of improvement hereinafter set forth, illustrated in thepreferred form in the accompanying drawings and more particularlypointed out in the appended claims.

In the drawings: Figure l is a view in elevation of the improve-5l gearshift mechanism with the casing shown in section; Fig. 2 is a plan view;Fig. 3 is a view similar to a portion of Fig. l and illustrating amodification; Fig. 3 is a detail view of parts shown in Fig. 3; Fig. 4is an enlarged longitudinal section; Figs. 5 and 6 are transversesections on the lines 5-5 and 6-6 respectively of Fig. 4C; and Figs. T,8, 9, 10 and ll are detail views illustrating different positions of theshifter actuating member or ram.

The engine l of the automobile operates the transmission shaft 2 throughthe medium of the usual clutch 3. Shaft 2 operates the car through themedium of suitable transmission gearing of selective type arrangedwithin a casing 4. Preferably the present improved shift mechanism forcontrolling the operation of the transmission gearing is arranged withina cast metal casing 5 which is open at the bottom and which is mountedupon and closes an opening in the top of the transmission casing Ll. I

The improved shift mechanism is more particularly applicable to thattype of transmission gcaring having two sliding gears 6 and 7, one ofwhich is provided with a clutch member S, and each of which is adaptedto be set in a central neutral position and be shifted in oppositedirections from the neutral to two different active positions. Themovements ot' these two gears are effected by two shift levers 9 and l()which are arranged within the casing 5 and are prefer* ably mounted upona common pivot pin ll. ln the form shown, the levers are provided withhubs which abut against each other and against the side walls of thecasing 5, as shown in Fig. 5. The lower arms of the shift levers areprovided with depending rounded ends which engage vertical slots in twoblocks or members l2. The latter are provided with depending forks 18which enga ge grooves in the hubs of the gears 6 and 7, and are fixed totwo horizontal guide rods 14 which reciprocate longitudinally in Ythebearings l5 and 16 formed in the lower portion of the casing 5.Spring-pressed detents 1T cooperate with V-shapednotches 18 in the guiderods 14 to yieldingly hold the shift levers and gears in their differentacltive and neutral positions.

A common actuating member or ram is provided for the shift levers 9 and10 and comprises the transversely adjustable, 10ngitudinally movableblock or member 19 which is slidably mounted in theI casing 5,

form shown.J is arranged in trent oit the shift levers, is provided atits upper and lower portions with a series oft iezi1.i.i.iai.tllyprojectingT tappets 20, 2l and 22 Vwhich are arranged to contact nf'iththe arms oil. the

levers and shift the same in opposite directions. ln the :torni shown.the actuating;A member 19 is provided with a single tappet 2() which isadapted to cooperate with the lower arm ot either shift lever and, atits upper edggd the actuating' member is provided with tivo tappetswhich co-act respectively` with the upper arms ol. the levers. Theactuating;v n'ieinber or ram is also pro vided with a series o i" cams,three of these cams,v 23, QllA and being; provided in the preferred formshown, lllach cam has 'two oppositelv inclined Working faces a and anintermediate central recess or seat` l) and are arranged to cooperatewith central. torivrnfdlv projecting' lugs or arms 2G :termed upon theshi'tt levers 9 and lll. lily aligning one ot' the cams with one oil'the shift levers and niovingi` it toward the axis olf' the lever, one orthe other of the inclined laces will, il? the shift lever has been movedfrom its new tral central position to either el? its active positions.engage the arm and restore it and the gear actuated thereby to neutralposition. Also, the engagement ot the recess or seat Z5 ot the cam Withthe rounded end ot the lever arm 26 will serve to lock or hold the leverin neutral position and the parte are so arranged that whenv evertheactuator is operated. to move one olE the shift .levers and its e ar toactive position, the other lever Will at such time be positioned andlocked in neutral position by one of the cams. rllee earns and tappetsare also so arranged that as the aetuatinginenn ber or ram is movedtoward the shift levers.. one oli the latter will be neutralized andloelred in neutra1 position by one of the cams l'ie'tore the otherleif'er is set` in active position bv one oil: the tappets.

lts most clearlv shown in llipgs. 7, 8, 9.. l() and ll'. the tappets andcams are disposed in different positions t.ansversel v of the actuatinn`ineinl'ier or ram 19, no tvvo of these elements being in alignment, andsuitable means are provided 'for adjusting the actuating); membertransversely to selectiveljT position the cams and tappets relatively tothe shift levers. Means are also provided .tor reciprocatin g5 theactuating' member lonh gitudinallv to effect the shilt of the levers andAgea-rs.

ln the forni shown. a rod E27 projects laterally from the actuatingmember or ram 19 `(3 olf the lever Leonesa through a longitudinal slot28 on the side of' the easing 5. lhe outer forked end oin this wrodslidably engages an elongated crank pin ,or rod 25) which is carried bytwo cranks 8U. 'llhe latter aro lined to a horizontal shaft 3l whichextends lore and att el' the machine and is jonrnalt-id in suitablebearings 32. An up ardly projectingr crank 33 on the fon ward end of theshaft is connected by a link 3s to a downwardly projectingl crank 35earried by a shaft C156. rlhe latter is preferably arranged adjacent orextends through the steering post 37 oit the car and is provided at itsupper endn'ith a hand lever 38 adjacent the steeringy wheel 3S). By adjlisting.;r the lever 3d.. the driver ot the car can position theactuatingmember or rain in any one of a number oit diierent selectivepositions which, in the form shown, correspond respectively to neutral.Jreverse and 1st, 2nd and 3rd speed positions ot the transmissionmechanism.

A crank arm 4:0 is provided :tor shitting the actuating member lf)longitudinally. This crank arm is lined to a shalt fl-1 journaled in anupwardly projecting part of the casino; 5. and its lower end is providedwith a rounded or cylindrical head which en gages a horizontal slotformed in a projection on the 'forward part olf the actuator. Crank arm40 is provided with an upwardly projecting' lue' 43 which engages a stopscrew le that is adjustablv threaded through the wall et the casing. .Ilspring-pressed plunger @lli guided in a sleeve 4G on the casing. engagesthe lug t3 and holds the crank arm 140 and actuating member l5) no1mallv in the retracted position shon'n. The member lf) is, ot course,free to be adjusted tranf nwrseljVIV independently ot the crank arm.(lne projecting' end of the shalt el is provided with a horizontal crankAll' which is connected bv a depending linl i8 to a horizontal crank arm/l-Sl upon a transverse shaft 50. Theshalt is provided with a orlr 5lfor operating; the clutch 3 and the usual clutch pedal 52 is connectedto the shaft. llie crank arm i9 is preferably pro-- vided with a pinwhich engages an elongated slot 54k in the linlr 48. so thata lostmotion connection is provided between the clutch pedal and the gearshitting' actuator .19. The driver ot the car can slightly depress thepedal to disenofarfei the clutch Without moving; the `Wear shiftingractuator, but continued pressure upon the :toot pedal. Will move themember 19 to position the les 9 and l0 and gears controlled thereby` inaccordance With the selective .setting of the nctuetinnr member.

ln the `neutral position of the actuator. shown in Fig. 7, two of itsearns 23 and 24 are respectively in line with levers 9 and l0, so thatwhen it is operatedthe earns will cooperate with the lugs 26 of thelevers to position and lock the levers and gears ink neutral position.In any of the other positions of the actuator, as is clear from aninspection of Figs. S, 9, l() and ll, one of the cams will be in lineWith one of the levers, and one of the tappets in line With the otherlever, so that one lever and gear are neutralized when the actuator ismoved longitudinally, and the other lever and gear are set in thedesired active condition. lt should also be noted that the neutralizedcams are so arranged that they will position one of the levers inneutral position and lock it in such position before the other lever ismoved to an active position, so that there is no possibility of thegears being improperly set. Preferably, as shown, the lug- 42 of theactuator is provided on its lower face with a rib which, as theactuating member is moved longitudinally, is arranged to engage one of aseries of slots 56 formed in the plate 57 and which assist in accuratelypositioning the actuating member or ram, although with the arrangementof cams and tappets shown, it is not possible to operatively move theactuator until it has been properly adjusted.

Instead of providing a lost motion connection between the clutch pedaland the gear shifting actuator' 19, the latter may be operated by an,independent pedal 5S, as shown in Figs. 3 and 3a. In this form, thepedal 5S is mounted on a sha-ft 59 which is journaled in suitablebearings on the casing 5, and a cranl: arm 60 on this shaft is connectedby a link 61 to the crankarm 47 on the shaft 4l. The foot-piece 6&2- ofthe' pedal is arranged adjacent and in front of the foot-piece 63 of theclutch pedal 52. `With this arrangement, the driver' may depress thefoot-piece 68 slightly" to open the clutch Without moving the gear shiftmechanism, but when the foot-piece 63 is further depressed, theoperators foot can also engage the foot-piece 62 of the gear shiftingpedal 58.

Means are also preferably provided for locking the gear shift mechanismagainst unauthorized manipulation. For this purpose, the easing 5 isprovided with a heavy raised portion 64 which projects upwardly throughthe floor 65 of the car, and a keycontrolled lock 66 of the Yale type ismounted therein. The barrel of the loe-k is provided at its inner endwith a crank 67 which is connected by a link 68 to a locking bolt 69arranged Within a vertical bore formed in the projecting portion 64 ofthe casing. This bolt is arranged to engage either one of two seats 70formed in the upper face of the gear shifting actuator '19 and whichpreferably corresponds to the neutral and reverse positions of theactuating member. By means of this locking device unauthorized operationof the transmission mechanism and consequently of the car is prevented.

Obviously changes may be made in the details set forth Without departurefrom the essentials of the invention as defined by the claims.
